Summary: [14/15 Regression] ICE with select type, type is
(character(*)), and substring
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: anlauf at gcc dot gnu.org
Target Milestone: ---
The following code fails for me with latest 14-branch/15-release candidate:
program p
implicit none
class(*), allocatable :: c
c = 'abc'
select type (c)
type is (character(*))
print *, c
print *, c(2:2) ! ICE

8 | print *, c(2:2) ! ICE
| 1
